D-antigen ELISA results of storage freezing treatments. IPOL (panel A) and VeroPol (panel B) were subjected to freezing treatments mimicking vaccine storage (1 day at −20 °C [scenario 1] and 7 days at −20 °C [scenario 2]) and tested by ELISA, with untreated vaccine included as a control. Error bars indicate the standard deviation. Statistically significant differences found by ANOVA and calculated p-values based on multiple comparisons analysis are indicated for IPOL in panel A: **p < 0.0001 and * p = 0.048.
